We have examined the yielding and fracture behavior of Zr57.4Cu16.4Ni8.2Ta8Al10 metallic-glass-matrix composites with a small volume fraction (similar to 4 pct) of ductile crystalline particles under quasi-static uniaxial tension and compression and dynami ...
The current research extends our previous work on brittle fragmentation of a one-dimensional bar [F. Zhou, J.-F. Molinari, K.T. Ramesh, A cohesive-model based fragmentation analysis: effects of strain rate and initial defects distribution, International Jo ...
Three-dimensional (3D) numerical simulations are performed to investigate the mechanical properties of ceramics under impact compressive loading. A microcracking model considering the stochastic distribution of internal defects in ceramics is developed. Th ...
Three-dimensional numerical simulations are performed to investigate the dynamic tensile properties of ceramics, using explicit dynamic FEM and cohesive element techniques. A micro-cracking model considering the stochastic distribution of internal defects ...
The microstructure of commercially available nanocrystalline (nc) electroplated Ni foils is studied by means of Xray diffraction and transmission electron microscopy. It is shown that the microstructure is inhomogeneous and batch-dependent. Tensile propert ...
The constitutive response of a Sigma9(221) symmetric tilt grain boundary in copper is investigated with an atomistic quasicontinuum method under tension and shear. The maximum strength is found to change with the deformation mode triggered at the interface ...
The possibility of decreasing ultimate tensile strength associated with increasing fiber/matrix interfacial sliding is investigated in ceramic-matrix composites. An axisymmetric finite-element model is used to calculate axial fiber stresses versus radial p ...
The fracture strength of silicon nanowires grown on a [111] silicon substrate by the vapor-liquid-solid process was measured. The nanowires, with diameters between 100 and 200 nm and a typical length of 2 μm, were subjected to bending tests using an atomic ...
Floating production, storage and offloading systems (FPSOs) have been widely used for the development of offshore oil and gas fields because of their attractive features. They are mostly ship-shaped, either converted from existing tankers or purposely buil ...
An assessment of the true stress-true strain relationship has been done by means of tensile and small ball punch tests on austenitic and tempered martensitic steel at room temperature. A finite element model was developed and validated to calculate the for ...
